The SG-21 pairs African Bubinga back and sides with the OM Hybrid, one of the three Studio Goose bodies. Boucher builds the series for players who want an accurate acoustic sound on stage and in the studio, and Robin Boucher selects each top himself: here it is AAAA Adirondack red spruce, the species that grows around the workshop in Berthier-sur-Mer, Quebec. The neck has a modified V profile with a 1.750" nut and joins the body at the 14th fret.
For the same wood on another body, look at the SG-22 Dreadnought or the SG-23 S-Jumbo. Bubinga figure varies from one guitar to the next, so the photos show one example.
Boucher's option packs can change the finish, add a pickup or a cutaway, step up the top grade or dress up the trim, and they are listed below.
